'E wo ink-distributing rolls are indicated respectively at Q5, 25. One of them is mounted in cooperative engagement with one pair of rolls 12, while the other is similarly mounted in cooperative engagement with the other pair or' rolls 12. The two (listributing rolls are the same in the matter of construction and arrangement, and a description oit' one will be sufficient for both. Each roll 25 is mounted upon a rod 2G. The ends of the rod are mounted in sockets 2T formed in bushings 2S. One orP these bushings is shown detached by 4ig. 5, but the arrangement of one end oi the rod Q6 in one of these bushings is shown in longitudinal section by Fig. t. The bushings 2S are mounted in the trucks 15 in suchv manner as to be adjustable tor the purpose of adjusting the distributing roll with relation to the inling rolls. It is necessary to keep the periphery of the distribu'tingroll against the peripheries of the inling rolls,

' and it is necessary to vary the adjustment of the distributing roll from time to time because the inling rolls are, in practice, customarily covered with a composition of sott material which shrinks. For this purpose the trucks are provided with parallel surfaces 29 which in the present instance are afforded by ears 80. The bushings are provided with parallel surfaces 31 which are adapted to have sliding engagement with the surfaces 219. These surfaces permit the desired adjustably of the bushings to carry the distributingl roll toward and from the inlring rolls and at the same time prevent rotationvof the bushings. rlhe bushings are further provided with lips or flanges 82 which are arranged against the inner sides of the ears 80, as shown by Fig. i. The bushings are bored, as indicated at for the reception of clamping bolts 3ft. The clamping bolts are inserted through washers from the outer sides ot' the trucks and through the bores 33 through which they er:- tend loosely and intothe ends oi" the rod Q6 which are internally screw-threaded for cooperative engagement with the threads oi' the bolts. The length of the bushings is slightly less than the thickness oit' the ears 30, and consequently when the bolts 3e are tightened the bushings are clampedtightly with relation to the trucks by cooperation of the lips 32 and washers 35, the bushings and washersbeing drawn together by the bolts and by the rod 26 whose ends are seated in the bushings. The length of the distributing roll is Yconsiderably less than the distance between the trucks 15, and the rolls are movably longitudinally with relation to the rods.

For the purpose of imparting longitudinal movement to the distributing rolls, cooperative screw-threads are provided which cause such longitudinal movement in consequence oil rotation ot' the distributing rolls. As shown by Fig. 3, one end of the distributing roll is provided with a bushing 36. This bushing is rigid with relation to the roll and 'formed with an internal screwthread 37. The complement-al screw-thread for engaging that at 37 is indicated at 38 and is formed upc-n a sleeve 39 which is pinned. or which may be otherwise affixed upon the rod 21%. It is necessary to1 provide these screu-tln'eaded elements at only one end of the roll and the other end may have a` smooth cylindric bearing upon the rod 26. It is desirable to restrict the length of the screw-threaded elementsso that they may become unscrewed or detached from each other without movino the ends of the roll into engagement with other parts of the mechanism, because otherwise the roll might become bound against some other part of the mechanism in case it turned more Jr'reely in one direction than in the opposite direction. rlhe length oi' the rscrew-threads 3i' and 38 is restricted for this reason, and theyv are adapted to become detached from each other without causing the ends of the roll to engage the trucks 15 or bushings 2S. Now, therefore, if the distributing roll should turn more freely in one direction than in the opposite direction its internal screw-thread would in time become entirely unscrewed from the thread 3S. I have provided means for causing the screw-threads to become 'operatively engagedfafter having become disengaged, for the purpose of causing the distributing roll to movelendwise in the desired manner after having become detached from the `thread 38. Reinforcement of the screw-threads is caused by helical springs indicated respectively at 40 and 41, the spring 40 being mounted upon the sleeve 39 at one end 'of the rod 36, and the spring 41 being mounted upon the 'opposite end of the rod. The springs act as follows :HVhen the distributing roll moves endwise toward the spring 40 it engages the spring before the screw-threads become disengaged from each other, thereby compressing the spring. It the endwise movement is suificient to carry the screw-thread 37 beyond Vand out of engagement with the thread 38, endwise 4movement of the distributing roll will cease,

notwithstanding continued rotative Inovement of the roll. Upon a reversal of rotative movement, the screw-threads will become automatically engaged with each other because of the force exerted Yupon the roll by the spring 40. The roll will Vthereupon move endwise in the opposite direction toward the spring 41, and ifits endwise movement in this direction should carry the screw-thread 37 beyond the thread 38 the spring l1 would be compressed, and upon the next reversal of rotative movement the iio sijn'iing would cause the Ascrevv-threads to again beeoine operatively engaged there-` with. i

Although the invention is illustrated as employing two inling rolls l2 for each dis"` tributing roll 25, it is apparent that the distributing roll and the mechanism lor causing its endwise inoveinent are adapted to be embodied in substantially Athe saine 'forin if only one inling roll were employed.`

said invention and described a way o'l ton` strueting and using the same, although without attempting to set forth all the lorms in which it may be made or all the modes oli its usej what I elaiin is:

l. In a printing press, the Combination with a chase, an inling roll therefor, and eoolierative trucks for said roll; oilE a roll for distributing the ink upon said inking roll, means ineluc'ling clamping inernbers for sup porting said distributing roll, said trucks having slideways for said clamping 1neinbers, whereby said distributii'ig roll may be adjusted toward and li'roni said inling roll, said clamping members having flanges bean ing upon the inner sides of said trucks, and

means eoperating with the outer sides of said truck or pressing said flanges against the inner sides of the trucks `to secure the clamping ineinbers to the trucks.

2. In a printing press, the combination with a Chase, an inking roll therefor, and cooperative trucks for said roll; of a roll for distributing the inl upon said inling roll, a 40 rod extending through and beyond the ends el said distributing roll, cap members engaging the end laces of said rod, said truck having slideways lto receive said cap ineinbers, whereby said distributing roll is adjustable toward and from saidinkiiig roll, said cap ineinbers having flanges bearing `upon the inner `sides of said trucks, and

screws extending toward eaeh otherl thron gh the outer ends olf said cap ineinbers and into the ends of said rod, said rod being internally threaded `for cooperating with said sere/ws, said screws having heads at their outer ends :l'or bearing against the outer sides olf said trucks to clamp said :flanges relatively to said trucks, and to clamp said rod relatively to said cap lnenibers d In testimony whereof l haveal'lixed niy signature, in presence of two witnesses.
